There
are certain devices that watch for tornadoes for us. Meteorologists rely on
weather radars to help keep watch of storms. If there is a threat of a
tornado, they will inform the public as soon as possible. This is called a
tornado warning. Doppler radars across the country are used to detect air
movement toward or away from the radar. Early detection of increasing
rotation during a thunderstorm can allow people to know that there is a
chance of a tornado being formed.These Doppler radars allow lifesaving warnings to be issued before
the tornado forms.
